أثر تمرينات الجهد البدني القصوي وفقا لمؤشر النبض و أثره على حجم عضلة القلب و إنجاز ركض 1500 متر تحت 20 سنة

Abstract EN

For every maximum physical effort for a sports competition that has its own adaptations to the functions of different body systems, the activity of the 1500-meter running has functional responses and adaptations that differ from other track and field activities.

Based on the field academic experience of the researcher, the researcher observed that one of the reasons for the low achievement in the activity of the 1500-meter running in Iraq during recent years, its deterioration compared to the Arab and continental levels, this activity needs physical preparation commensurate with their capabilities and abilities according to the activity and its requirements, and this prompted the researcher to search for the preparation of appropriate training requirements for this type of activity that needs physiological requirements and which gives physical preference according to the two pulse indicators (120 z / D) or (130 z / d).

The research aims to identify and prepare the effect of maximum physical exertion exercises according to the pulse index and its effect on the size of the cardiovascular and the achievement of a 1500-meter running under 20 years old.

The researcher adopted the experimental approach with equal groups.

The research community determined that 1500 meters running for youth and by (16) runners under the age of 20 years, and it applied Maximum physical exertion exercises according to the pulse index and its effect on the size of the cardiovascular on the experimental group for a period of eight weeks with three training units per week.

The SPSS statistical package was used to process the data and obtain the results, from which the researcher reached the most important conclusions, which is that the maximum physical exertion exercises according to the pulse index have a positive effect on the adaptation and normalization of the size of the cardiovascular and on the achievement of the players, which indicates the effectiveness of the exercises during the period of special preparation of the experimental group.
